There are several things you can do to prevent birds from nesting under your panels.
Fortunately, there are some simple, non-invasive options.
Perhaps not the most attractive option. Bird mesh is usually made of galvanised steel which wouldn’t look very nice next to your expensive solar panels. This will prevent birds from being able to get under your solar panels.
However, please note that you cannot fix bird mesh to the panels themselves as it will void the solar panels warranty, bird mesh would have to be clipped to the roof mountings.
Not very humane! But it will stop pigeons from nesting underneath your solar panels.

Pigeons like to nest nearby a source of food. If they do not have a nearby source of food then they’re much less likely to view your roof as a good place to nest!
